3 Claims.

This invention relates to carding machines, and more particularly forproviding a device in the form of an attachment to be used inassociation with a calendar roll or calendar mechanism for parallelizingthe fibers in a card sliver.

An object of this invention is to provide an attachment forparallelizing the fibers in a card sliver which may be mounted on thepresent structure of a carding machine and may if desired, be positionedeither on the input or the output side of the calendar roll, between thedoffer cylinder and the calendar roll, between the calendar roll and thecoiler mechanism, within the coiler head, or at any point from where thecard web leaves the doffer up to the point where the card web or sliverenters the receiving can.

Another object of this invention is to provide an attachment of thiskind which when mounted on the carding machine will eliminate thesubsequent processing of the sliver through a drawing frame.

A still further object of this invention is to provide an attachment ofthis kind which includes pairs of rolls, a slidable mounting for therolls and a weight connected to certain of the rolls for placing thesliver under the desired pressure as it passes through the rolls.

To the foregoing objects and to others which may hereinafter appear, theinvention consists of the novel construction, combination andarrangement of parts as will be more specifically referred to andillustrated in the accompanying drawings, wherein is shown an embodimentof this invention, but it is tobe understood that changes, modificationsand variations may be resorted to which fall within the scope of theinvention as claimed.

In the drawings:

a Figure 1 is a top plan of an attachment constructed according to anembodiment of this invention, the attachment being shown mounted on acarding machine which is shown in fragmentary form,

Figure 2 is a sectional view partly in detail taken on the line 2-2 ofFigure 1,

Figure 3 is a fragmentary end elevation of the attachment,

Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure1, and

Figure'5 is a fragmentary sectional view taken on the line 5-5 of Figure1.

Referring to the drawings, the numeral l0 designates generally the frameof a carding machine wherein a pair of calendar rolls II are rotatablymounted. The rolls H are mounted on shafts l2 and it which are journalled in the frame structure It! and the shaft I2 is preferably extendedlaterally and is provided with a gear M which is fixed thereon. The gear14 meshes with a gear I5 mounted on a shaft I6 which may be connected toa suitable driving means or other part of the card machine and wherebythe desired rotary movement is provided for the calendar rolls II.

In order to provide a means whereby the sliver of cotton passing betweenthe calendar rolls ll may have the fibers thereof made parallel, I haveprovided a parallelizin attachment including a pair of substantiallyU-shaped brackets generally designated at E1. The brackets ll have oneleg l8 thereof disposed in a horizontal position for engaging on ahorizontal frame part I9 which is formed as part of the frame structureIll. The leg I8 is secured to the supporting part l9 by fasteningdevices 29. In the present instance, the bight 2| of the bracket I1 isdisposed adjacent the lower calendar roll II and the upper leg 22extends real'wardly and in parallel relation with the lower leg 18. Thetwo brackets ll are positioned in the present instance, between thecalendar rolls l l and the doifer cylinder.

Each upper leg 22 has a pair of guide members 23 and 24 for bearingsmounted thereon. The guide member 23 is provided with a slot or recess25 opening through the upper end thereof and upper and lower bearingmembers 26 and 21 respectively are slidable in the slot 25 which forms aguide for the bearing members 23. The guide member 24 is also providedwith a guide slot 28 and upper and lower bearing members 29 and 30 areslidable in the guide-way 28. The guide members 23 and 2 1 may besecured to the upper side of the horizontal leg 22 in any suitablemanner. An upper roll 3! is disposed between the two bearing members 23and is provided at the opposite ends thereof with trunnions or stubshafts 32 which are journalled in the bearing members 26. A second upperroll 33 is dis posed forwardly of the first roll 3| and is provided atthe opposite ends thereof with trunnions 34 which are journalled in thebearings 29.

A lower forward roll 35 which is provided at one end with a trunnion 3!:is positioned below the forward roll 3| and the trunnion 36 isjournalled in one bearing 21. A shaft 3'! is formed with the roll 35 andextends from the roll 35 opposite from the trunnion 36. A gear 38 isfixed to the shaft 3'! and is adapted to mesh with a gear 39 which ismounted on a stub shaft 40 carried by the frame structure H). A secondor forward roll ti is disposed below the roll 33 and is provided with astub shaft or trunnion d2 journalled in one of the bearings 3 A driveshaft G3 is carried by the opposite end of the lower roll li and thedrive shaft 53 has a gear M fixed thereto which meshes with the gear 35A second gear :25 is mounted on the drive shaft Q3 and meshes with agear 36 carried by a stub shaft ll. The gear 43 also meshes with thegear l lso that rotation of the calendar rolls M will effect rotation ofthe paralleling rolls 3t, 33, 35 and ii. The gear Gd is substantiallysmaller in diameter than the gear so that the two forward rolls 3! and35 are rotated at a speed less than the rolls 33 and ii. In this mannerthere will be a drawing of the fibers which will effect a parallelizingof the fibers prior to the time the sliver enters between the calendarrolls l l.

In order to provide a means whereby the upper or idler rolls 3! and 33may be held in contacting relation with the sliver and so that thedesired pressure may be applied to the sliver, I have provided a pair ofsaddle members :53 which engage over the trunnions 32 and Each saddlemember 63 is provided with an arcuate recess is forming a seat toprevent endwise movement of the saddle during the rotation of the idlerrolls 3i and A weigh is provided for each saddle it and the weiglt ismounted on the lower end of a vertical roll -'Ihe upper end of the rollEl is provided with an eye 52 in which the saddle i8 is looselyreceived.

A trumpet or sliver compressing member 55; is disposed with the reducedend thereof confronting the two rolls 3! and and the flared end of thetrumpet 53 is secured to a vertical web or guard 54 w ion is providedwith angularly disposed opposite end portions A base plate extendsrearwardly frorn the web or guard 5 and a plate or flange El is securedto the lower end of the web or guard Ed and extends forwardly therefrombeing secured by means of a fastening device 583 to the upper leg 22 ofa bracket 5'5. A depending plate or guard is carried by the rear edge ofthe base plate 5 5 and coacts with the web or guard in providing a meansto prevent the stray ends of fiber from engaging between theparallelizing rolls adjacent the ends of these rolls.

A condensin guide 8% is disposed between the output side of the rolls 33and ti and the input side of the calendar rolls M. This condensing guideGil is formed of upper and lower frustotriangular plates 5! which areconnected together by end plates 62. The large end of the so confrontsthe output sides of the rolls and ll. The guide SE? is supported in thedcsired position relative to the two rolls 33 and 4-5 by means of asupporting bar 53 which is secured to the lower plate iii.

In the use and operation of this attachment, the two bracket members iiare mounted on the frame part Ed by tl e fasteni g devices The gear ismounted in a position to mesh with the calendar gear id which iscommonly known as the carrier element. The rolls 3!, and ll are thenmounted in th respective bearings which are slidably mounted within theguide slots 25 and E3 of the bearings 23 and 2%. The carding machine isthen operated in the usual manner and as the sliver passes from thedoiier cylinder into the calendar rolls ii, the sliver willpass throughthe trumpet 53 and between the first pair of rolls 3i and 35. The lowerroll is positively driven through the hereinbefore described gear trainwhereas the upper roll 3| is an idler roll.

The two weights 5% will maintain the upper roll 3. in the desiredcontacting relation with the sliver as it moves between the two rolls 3|and 35. The gear train is so arranged that the lower forward roll M willrotate at a speed greater than the rear roll 55 so as to effect adrawing or pulling on the fibers in the space between the two rolls 35and M. This drawing or pulling will have the effect of parallelizing thefibers which will then pass through the condensing guide into thecalendar rolls.

ihe use of an attachment of this kind on a carding machine will make itunnecessary to pass the sliver through a drawing machine, the purpose ofwhich is to make the sliver fibers parallel. It will therefore beapparent that this attachment will eliminate the drawing process whichat present is performed by a separate machine. This attachment may bemounted on the present structure of a carding machine Without ai fectingthe arrangement of the parts on the machine and at the same timeeliminate the subsequent step of making the fibers parallel by thesliver through a drawing process.
